I assume they are doing studies but wish they had done more before "recreationalizing it". IMO there have been enough study results to use it medically. Unfortunately--it is not even being incorporated medically in very smart ways yet on balance. We are so behind the curb because of stigma. Yes it can be dangerous. So is my Xanax, all the Oxycotin and Percoset I was on when I was in the hospital in 2015 and so are so many other drugs....As far as it causing schizophrenia, anxiety, etc--was it the trigger or was that something that was already within but was just brought to the surface more obviously? And do the effects wear off when you stop?? I am not sure. All possible.
